IMPROVEMENT lN LOOM-SHUTTLES.

Specification forming part of Letters Patent No. 188,460, dated March 20, 1877; application tiled July 26, 1876.

To all whom it may concern Be it known that I, CHARLES W. ANDER- SON, of Pawtucket, in the county of Provi dence and State of Rhode Island, have invented certain new and useful Improvements in Loom-Shuttles; and I hereby declare that the following is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of this specification. I

Figure l is a view of my improved loomshuttle, showing the cop on the skewer, and the thread passing forward to the yarn-eye, and also the detecter, by which the yarn isbroken when the warp-threads are not properly raised or lowered. Fig. 2 is a side view, partly in section, of my improved loom-shuttle, the plate covering the detecter stop-motion being shown removed, so as to exhibit the parts of the mechanism.

This invention consists in the peculiar arrangement of a detecter with a loom-shuttle, so that When any threads ot' the Warp are not properly raised, or when loose threads adhere to the warp, the arm ofthe detecter will come in contact with such obstruction and the mechanism break the yarn, when the loom will be stopped by the shuttle `stop-motion now used on looms, so that if any of the Warp-threads break, or are not sufciently raised, or a loose thread becomes attached to the Warp, or any other irregularity in the Warp takes place, the detecter Will break the yarn, and the stop-motion Will at once stop the loom.

All the weaving of imperfect cloth Will thus be prevented, all the time and labor in picking outwill be saved, and the loom will become more elcient and automatic.

In the drawings, a, is the shuttle proper. b is the skewer, and d the cop of yarn. -E is the yarn-eye, through which the -yarn passes. Over the yarn-eye the vibrating arm f, provided With an eye, is secured, so that when the arm is moved forward or backward beyond the eye the yarn is firmly held, and as the shuttle is moving through the loom, is caused to break, which breaks will usually take place outside the yarn-eye.

The arm j' is connected by a Wire with the it is obvious that the arm g may be hinged` at its lower end, and the wire connecting the armfwith the saine be hinged above; or the detecter arm may be made to slide in a groove, and provided with springs, by means of which it is made to return to its normal position.

The shuttle is shaped as shown in the drawings, so that While the detecter-arm does not extend above the average height of the same, it does extend above the shuttle at the place Where it is secured. The detecter-arm must be light, and the spring arranged to yield freely, and still hold the arm, so that the draw of the shuttle will not affect the same, While even a loose piece of yarn coming in contact With the detecterarm will break the .thread and release the vshuttle stop-motion, and thus stop the loom.

It frequently happens that one or more Warp-threads in a loom break and become entangled. Shuttles as at present constructed pass through such obstructions, and Where one Weaver attends four, six, or more looms, considerable bad cloth is at times woven,which,

as soon as discovered, must be picked out by hand and the warp carefully cleaned. This requires time and careful labor, and the loom must be .stopped until the operation is completed.

By arranging my detecter on the shuttle any imperfections in the Warp are at once discovered. The filling-yarn is broken and the loom stopped, when the cause will be atonce apparentto the Weaver, and can be readily removed and the loom started.

Much time is thus saved, and all the picking out avoided, while only perfect cloth will be woven.

The detecter can be cheaply applied to any kind of shuttle, and more looms can be attended, When provided with this improvement, by one weaver than without the same.

Having thus described my invention, I
